Specification of Letters Patent.

Application filed February 17, 1914. Serial No. 819,271.

To all whom it may concern Be it known that I, CHARLES A. KIRBY', a citizen of the United States, residing at La Fargeville, in the county of Jefferson and,

State of New York, have invented new and useful Improvements in Wagon-Brakes, of which the following is aspecification.

This invention has relation to wagon brakes and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a brake mechanism of simple structure especially adapted to be applied to the running gear of a farm wagon and having a brake beam provided with shoes adapted to encounter the peripheries'of the. front wheels of'the running gear. i

A furtherobject of the invention is to provide in connection with a brake mechanism as above indicated, means for operating the same from the tongue of the running gear. That is to; say, when the tongue is pulled in a forward direction, the brake beam and shoes are moved away from the forward wheels but when a backing strain is applied to the tongue, the beam is'moved in a forward direction whereby the shoes are automatically applied to the wheels.

A further object of the invention is to provide in conjunction with a brake mechanism as above indicated, means for locking the parts against relative movement whereby the running gear may be moved in a forward or backward direction by strains or pulls applied to the tongue without operating the brake mechanism.

In the accompanying drawing-Figure 1 is an under plan View of the front axle and attached parts of a running gear with the brake mechanism applied. Fig. 2 is a longitudinal sectional view. Fig. 3 is a detailed plan view of parts of the brake mechanism. Fig. 4% is a detailed transverse sectional view of the upper forward part of the mechanism.

As illustrated in the accompanying drawing, the front axle and sand board 1 of a wagon running gear are supported upon wheels 2 in the usual manner. Hounds 3 extend transversely across the axle and sandboard in the usual manner. Loops 4 are connected with the rear ends of the hounds 3 and a brake beam 5 is loosely mounted in the said loops. The beam 5 carries at its ends, shoes 6 which are adapted to encounter the peripheries of the Wheels 2. Clips 7 are mounted upon the axle and sand-board in Patented Dec. '1, 1915. V

the usual manner and braces 8 connect the J,

said clips with the forward end portions of the hounds 3. The-clips 7 are provided with lugs 9'upon which are fulcruined levers 10; The inner end portions of these levers overlap each other as shown in Fig.1 of the drawing. Rods 11 are connected with the outer end of the levers 10 and pass trans-" verselythrough the beam and are secured in adjusted positions with relation to the beam by means of nuts 12 which are screw threadedupon the said rods. The said nuts 12 are arranged in pairs and the members of the pairs are located at the opposite sides of the said beam.

Wedge-shaped blocks 13 are pivoted upon a bolt 14: which passes transversely through I the said blocks and the forward portion of the hounds 3. A tongue 15 lies-between the blocks '13 and is provided with elongated slots16, one of which receives the bolt 14:

and the other receives a bolt 17 which passes transversely through the forward portions of the blocks 13. An eye 18 is mounted'upon the under side of the tongue 15 and links 19 pivotally connect the said eye with the inner ends of the levers 10. Thus it will be seen that when the tongue 15 is moved'in a rear- -ward direction between the blocks 13, the

lnner ends of the levers 10 are swung rearwardly by the thrust of the links 19. Thus the outer ends of the said levers 10 are carried forwardly and the beam 5 is moved in a forward direction in the loops 1 and consequently the shoes 6 are brought in contact with the peripheries of the wheels 2.

It will be seen that the blocks 13 are pivotally mounted upon the bolt 14 and consequently the said blocks 13 may swing vertically between the forward end portions of the hounds 3 at the same time the said blocks are restrained against longitudinal movement with relation to the said hounds.

lVhen the tongue 15 is moved in a forward direction between the blocks 13, the parts connecting the said tongue 15 with the beam 5 operate in a manner exactly the reverse from that above described, whereby the brake shoes 6 are carried away from the peripheries of the wheels 2. Therefore, when a backing strain .is applied to the tongue 15, the brake shoes are automatically applied but whena pulling strain is applied to the said tongue, the brake shoes are in a similar manner disconnected or spaced from the peripheries of the wheels 2. Inasmuch as a great" portion of strain is trans mitted to the clips 7 when the brake shoes" are applied to the peripheries of the Wheels 2, the braces Sare provided which ,Willabsorb a greatportion of this strain or distribute the same, whereby the major pol: f

tion of the said strain"istransm'itted'to the iU- -r v i V in connection WIT/l1 a dev ce 'as'a'bove'descrioed, it is somet mes desirable to fixthe forward" end portions vof :th'eE hounds 3 and "from tllGfStllCl hounds to the 'aXle and sand tongue with relation to the blocks in order that the running gear may be freely hacked or pulled-ahead as desired. 'Su'cha'device is provided in conjunction with the present "structure 'and'it consistsiofa bail '20 which is pivotally connected Withthe blocks and Which-is adapted? to ,sW-ingdoWn over the upper end portion of a pin 21 carried 'by the tongue 15. The intermediate portion ofthe bail 20 may pass over the said pin when the tongue i5is pulled in a forward direction and consequently the brakeshoes are out of engagement Withthe peripheries of the Wheels'QQIA spring. actuated catch 22 is pivotally"mounted adjacent the loail which is automatic inits action andmeans are provided in connection'with saidbrake xgagement with the bail; 1
